Frequently Asked Questions

How should I interpret 14.0 Nm continuous at standstill (100 K) and 8.5 A on MSK071C-0300-NN-S2-UG0-RNNN?

It indicates sustained feed or holding torque with thermal reference (winding over ambient) of 100 K for guiding continuous-duty sizing. Its paired current clarifies drive sizing and copper-loss estimates for worst-case stall conditions.

Why choose natural-convection cooling on MSK071C-0300-NN-S2-UG0-RNNN?

The fan-less convection reduces parts count and maintenance while keeping thermal paths predictable for duty computations. It also offer retrofit blowers or liquid cooling when application duty cycles demand greater continuous thermal throughput.

How does the EnDat 2.1 singleturn encoder (S2, 2048 periods) on MSK071C-0300-NN-S2-UG0-RNNN enhance positioning?

It provides absolute position on startup and fine incremental signals per revolution to improve loop stability and eliminate homing routines. Its implementations in MSK motors specify system accuracy around ±20 arcsec depending on variant.

What does the 10,900 mH winding inductivity mean for MSK071C-0300-NN-S2-UG0-RNNN control performance?

Its higher inductance increases electrical time constant for smoothing current ripple and easing current-loop tuning at moderate bandwidths. It complements high-resolution feedback for stable servo behavior under variable mechanical loads.

How do the 240° rotatable power/feedback connectors help on MSK071C-0300-NN-S2-UG0-RNNN?

They permit cable exit to be oriented away from obstacles to simplify routing in compact or moving installations. It reduces strain-relief complexity and helps maintain bending radii on robot wrists or gantries.
